Function

PETH2_THEAE Catalyzes the hydrolysis of cutin, a polyester that forms the structure of plant cuticle (PubMed:20393707, PubMed:22183084, PubMed:25910960, PubMed:33387709). Shows esterase activity towards p-nitrophenol-linked aliphatic esters (pNP-aliphatic esters) (PubMed:20393707, PubMed:22183084, PubMed:25910960, PubMed:33387709). Capable of degrading the plastic poly(ethylene terephthalate) (PET), the most abundant polyester plastic in the world (By similarity). Can also depolymerize the synthetic polyesters poly(epsilon-caprolactone) (PCL), poly(butylene succinate-co-adipate) (PBSA), poly(butylene succinate) (PBS), and poly(lactic acid) (PLA) (PubMed:20393707, PubMed:22183084).[UniProtKB:D4Q9N1]^{[1] [2] [3] [4]}
